The Invoke-ADTAllUsersRegistryAction only works with PSADT functions that have a -SID parameter like Set-ADTRegistryKey and Start-ADTProcess is NOT one of them.
Some people use Start-ADTProcessAsUser but that only works when the current user is the one who launches the installation and only works for HIM/HER.
If you want to hit ALL USERS you'll have to look at something I wrote on this topic a few months ago.
